Abstract
The paper deals with steel structures of road bridges. Multidimensional dynamic stress diagrams are suggested for steel road bridges. The analysis and quantitative conclusions are presented for the trouble-free operation of complex loaded structures. The paper describes the spatial distribution of mechanical stresses in buildings based on the obtained data on the operation under various loads and the statistical distribution of different points and zones of the object. Acoustic stress measurements are carried out during the bridge operation, and mathematical distributions are obtained for all measured points. It is shown that in determining the entire array of loads, a criterion can be identified for the trouble-free operation of bridge elements and the structure as a whole. Mathematical distributions are obtained or all measured points. The criterion parameter Χ2 is introduced. It is found that the real three-dimensional distribution clearly describes the operation of various units and parts of steel road bridges. The findings confirm the proposed hypothesis about the possibility of such a description. It is noted that the real three-dimensional distribution well describes the work of various nodes, parts, parts of steel road bridges. The findings confirm our hypothesis about the possibility of such a description.
